i like the game because it doesn't take for ever to level and if you want you can prestige and keep leveling and getting titles so if you don't have a lot of time to play the game you don't suffer and if you have a lot of time you still don't suffer because you have a lot to do also there is a lot of challenges for the guns so it will keep you busy and there fun to get even if you don't have a lot of time you can just pick one gun and get the upgrades for that then enjoy the gun. recently my favorite thing to do is pull out my m9 pistol with my tactical knife attachment with marathon, lightweight, and commando perks with a sub machine gun as my main gun so i am really light. then i just get knife kills the whole game. you got to try it >:D
